This research suggested a method by which the driver space can be designed to best accommodate the driver's anthropometric characteristics. Three-dimensional manikins and a variable seating buck were developed and used for this study. Manikins were designed with 18 links comprising the 95th percentile male and 5th percentile female data. The seating buck was built to create various driving environments using the distance and the height between the H-point(hip pivot) of the seat and the AHP(accelerator heel point), the angle of the back rest, the angle of the steering wheel, the vertical distance of the steering wheel, and the location of the T.G.S.(transmission gear shift) knob. Measurements of each variable were collected with a coordinate measuring machine by positioning the 3-D manikin under various combinations of the design factors of the seating buck, which was constructed based on mid-size domestic passenger cars. The data were then converted to the joint angles of the driver. The combination of the measurements for an optimal driving environment is suggested by applying sets of the joint angles at which the driver feels comfortable.

대상사안에서 한국인은 유럽항공사(에어프랑스)의 초과예약으로 인하여 파리에서 서울행 항공기의 탑승이 거절되었다. 대상사안에서는 국제사법 시행 이후 국제항공운송계약의 준거법, 항공권의 초과예약으로 인한 탑승거절에 대하여 항공사가 부담하는 민사책임 등이 문제되었다. 운송계약이나 소비자의 상거소지 외에서 용역이 제공되는 계약이라고 하더라도 소비자계약에 해당하는 경우에는 소비자의 상대방이 계약체결에 앞서 그 국가에서 광고에 의한 거래의 권유 등 직업 또는 영업활동을 행하거나 그 국가외의 지역에서 그 국가로 광고에 의한 거래의 권유 등 직업 또는 영업활동을 행하고, 소비자가 그 국가에서 계약체결에 필요한 행위를 한 경우나, 소비자의 상대방이 그 국가에서 소비자의 주문을 받은 경우 등에는, 당사자가 준거법을 선택하지 아니하였더라도 국제사법 제27조 제2항이 적용되어 소비자의 상거소지법이 준거법이 된다(대법원 2014. 8. 28. 선고 2013다8410 판결). 이에 따르면, 대상사안에서 문제가 된 국제항공여객운송계약도 소비자계약에 해당하므로, 준거법은 국제사법 제27조 제2항에 의하여 상거소지법인 대한민국 법이 된다. 이는 로마협약(80/934/EEC) 제5조 제4항에서 운송계약이나 소비자에 대한 용역이 소비자가 상거소를 가지는 국가 이외의 장소에서 배타적으로 제공되어야 하는 용역의 제공에 관한 계약에 대하여는 소비자의 상거소지법의 적용을 배제하는 것과 반대견해로, 외국항공사를 이용하여 국제여행을 다녀오는 내국인이 점차 증가하고 있는 상황에서 내국인 보호에 커다란 이정표가 될 수 있다. 다음으로 초과예약의 관행을 긍정한다 하더라도, 항공사는 초과예약으로 인하여 탑승이 거절된 승객에게 적절한 대체항공편을 제공하여야 하고, 만약 그러한 의무를 이행하지 아니한 경우에는 민법상 채무불이행 책임을 부담한다고 판시하여, 항공사의 민사책임을 명확히 하였다는 점에서 의의가 있다.

This paper deals with an estimation method for sideslip angle by using an unknown disturbance observation technique in 4WS passenger car systems. Firstly, a 4WS vehicle model with 3DOF is derived under the constant velocity and same tyres properties. The vehicle dynamics is transformed into the linear state space model with considering the external disturbances. Secondly, and unknown disturbance observer is introduced and its property which estimating the states of system without any disturbance information is shown. Lastly, the estimated sideslip angle of the 4WS vehicle system is verified through numerical simulation.

This paper deal with a fault detection algorithm for front wheel passenger car systems by using robust $H{\infty}$ control theory. Firstly, we present a unified formulation of vehicle dynamics for front wheel car systems and transform this formulation into state space form. Also, by considering the cornering stiffness which depends on the tyre-road contact conditions, a multiplicative uncertainty for vehicle model is described. Next, the failures of sensor and actuator for vehicle system are defined in which the fault .lter is considered. From the nominal vehicle model, an augmented system includes the multiplicative uncertainty and the model of fault filter is proposed. Lastly by using $H{\infty}$ norm property the fault detect conditions are deefi.ned, and the actuator and sensor failures are detected and isolated by designing the robust $H{\infty}$ controller, respectively.

Main sources of increased vibrations and air noise on ship are main and auxiliary engines and ship ducts. The various ways of transfer of vibration energy and air noise in passenger cabin of a vessel require, in general case, of various methods of attenuation. The transfer of vibration energy from engines through a support requires, alongside with shock-absorbers, availability active shock-absorbers. The transfer of vibration energy and hydrodynamic noise on ship ducts requires availability, alongside with flexible muffler, active mufflers. The availability of air noise from working equipment can require, along with absorbent covers, of space systems of active noise control. In the given article it is spoken about the unified approach to formation of the block-diagram of active noise and vibration control. The complex approach permits to receive additional efficiency in reduction of noise in passenger cabin of vessels.

Most real world design evaluation and risk-based decision support combine quantitative and qualitative (linguistic) variables. Decision making based on conventional mathematics that combines qualitative and quantitative concepts always exhibit difficulty in modelling actual problems. The successful selection process for choosing a design/procurement proposal is based on a high degree of technical integrity, safety levels and low costs in construction, corrective measures, maintenance, operation, inspection and preventive measures. In this paper, a design decision support framework using a composite structure methodology grounded in approximate reasoning approach and evidential reasoning method is suggested for design evaluation of machinery space of a ship engine room at the initial stages. An illustrative example is used to demonstrate the application of the proposed framework.

The urban railway system is a convenient public transportation system, as it carries many people without increasing traffic congestion. However, air quality in urban railway environments is worse than ambient air quality due to the internal location of the source of air pollutants and the isolated space. In this paper, characteristics of particulate matter (PM) pollution in urban railway environments are described from the perspective of diurnal variation, chemical composition and source apportionment of PM. PM concentrations in concourse, platform, passenger cabin, and tunnel are summarized through an analysis of 34 journal articles published in Korea and overseas. This information will be helpful in developing effective policies to reduce PM pollution in urban railway environments.
